10m WSPR

As of about 1056z,  I closed down on 40m and have moved to 10m WSPR. It takes a few minutes for things to settle. On 10m, the cycle is as 40m i.e. 2W TX for 20%, followed by RX for 80%.

UPDATE 1112z: VK2KRR (16789km) has already been spotted and spots exchanged with FR1GZ (9724km) both ways. I have also been spotted in Brazil. A very good start on 10m WSPR today.

UPDATE 1138z: 4X1RF (3519km) has also spotted me. Local G4KPX (14km) was spotted with -4Hz drift at 1124z. I was too late getting into the shack to check the WSPR-X screen, but this must be due to aircraft coming into or leaving Lakenheath or Mildenhall. Normally Richard shows no Doppler.  With aircraft reflections you often see multiple traces with different Doppler shifts. WSPR decodes the trace with least Doppler or fails to decode if it gets confused, even if the traces are strong.
10m WSPR spots to 1150z today
Conditions on 10m are excellent today. I think USA 10m WSPR spots are a near certainty this afternoon.

UPDATE 1810z:  Surprisingly, not a single USA spot today on 10m WSPR.  Lots of spots of G4KPX (14km) with large Doppler shifts by aircraft movements in the Ely-Burwell area.

UPDATE 1425z: G4KPX (14km) was spotted not long ago with a huge Doppler shifted second signal as strong as the direct signal. The Doppler shift was about 20Hz or more. I think the direct signal decoded. No USA 10m WSPR spots yet.
